Spin-polarized supercurrents for spintronics

The past decade has seen dramatic advances in designing and building structures that combine the zero-resistance supercurrents of superconductors with the spin alignment of ferromagnets. The resulting spin-polarized supercurrents can propagate over long distances, and as a controllable source of spi...

Summary:The past decade has seen dramatic advances in designing and building structures that combine the zero-resistance supercurrents of superconductors with the spin alignment of ferromagnets. The resulting spin-polarized supercurrents can propagate over long distances, and as a controllable source of spin states, they hold tantalizing promise for spintronics, an emerging field that exploits electrons' spin degrees of freedom for electronic devices. Here, Eschrig discusses the spin-polarized supercurrents for spintronics.
